Identical bet, worse price
Big 6 and Big 8 win on exactly the same condition as placing the 6 or 8: the number must appear before a 7. The probability is identical at 45.45%. The only difference is what you get paid.
A place bet pays 7:6. Big 6 and Big 8 pay 1:1. Nothing else changes, and the house edge goes from 1.52% to 9.09% — roughly 6 times the cost for the same risk.
Why the box exists at all
The Big 6 and Big 8 boxes sit at the corners of the layout where a new player can reach them without help. Placing a number requires speaking to the dealer; Big 6 and Big 8 can be self-served. The convenience costs six times the house edge.
Some jurisdictions, notably in Atlantic City, require these boxes to pay 7:6, which makes them identical to a place bet. Where that is the case the trap disappears.
What to do instead
Tell the dealer you want to place the 6 or the 8. It is the same bet at 1.52% instead of 9.09%, and it takes one sentence.
